Is this teensy3.2 ref schematic correct ?

[Minege]

Hello,

I have found a teensy 3.2 custom board on github https://github.com/thewknd/teensy-boards/tree/master/Teensy 3.2 reference board clone
Here is a screenshot(Opened in kicad with https://github.com/sci-bots/teensy-3.2-clone.kicad):



Can i use this schematic as is, and create a circuit out of it ? ( By following the teensy custom board guidance )
Do you have any recommendation or improvements to do ?

Do you think i will encounter any problems if i order the pcb and assemble it ( Considering it is well assembled )

Are the components correct, and can i use generic components for resistance, ferric beads, diodes, and capacitors ?
I ask this because i saw that it is a bit different that the original teensy 3.2 one :

There are 2 different boards.
1. The Teensy 3.2: https://www.pjrc.com/store/teensy32.html
The schematic for this is: https://www.pjrc.com/teensy/schematic32.gif
you can buy the board in the PJRC store. But there are no gerber or similar pcb data published.

2. The Teensy 3.2 DIY Reference Board: https://www.oshpark.com/shared_projects/d3J03Zeb (https://www.pjrc.com/store/ic_mkl02.html -> Examples)
This board is designed by PJRC. But you can't buy the full board with all electronic parts soldered on it. Only the bare pcb trough oshpark. On the oshpark shop is an option to download the gerber files.

I have downloaded the gerber files and imported them into Eagle (6.6.0) and tried to copy the routing / pcb traces as exact as possible. The result is this github repo: https://github.com/thewknd/teensy-boards/tree/master/Teensy 3.2 reference board clone

And someone took the eagle files and imported them into Kicad and published the project here: https://github.com/sci-bots/teensy-3.2-clone.kicad

Last year a user spotted an error in the BOM from my github repo. This is fixed now in my github repo - but I think the github repo with the kicad project isn't updated. The part number for the 0.1 uF capacitor was wrong. But this did not affect the board design.

Hello HWGuy,

Thank you for your reply. I appreciate it.

I effectively wanted the bare pcb, but just to be sure that, when i solder the components on, it will work, and it is not an outdated board or something like that !

I tried to explain why a second schematic exits, which is a little different.

So... the board itself is not outdated. For the github repos, the one with the eagle files is up to date - the one with the kicad files i don't know. But i think both should be good (except the wrong 0.1 uF capacitor in the bill of materials). You can take the schematic and make your own circuit out of it.

Ok. got it.

Thank you very much !
